SILVERLIGHT and SQL SITE maintenance and development

We would like you to develop and maintain our Silverlight site [login to view URL] that contains our customer database and that visitors can access to buy online services. The SQL database is rather complex therefore solid experience is necessary not to damage its structure. Also it would be of benefit if you have experience with audio components of silverlight as we are generating audio wav files on this site that are then available for download after paypal payment - its a very interesting project with much potential to continue to expand for a long time - there is no time pressure - and a very friendly global team
